Average Heating Rate of Hot Atmospheres in Distant Clusters by Radio AGN: Evidence for Continuous AGN Heating
Average Heating Atmospheres Distant Clusters Evidence Continuous Heating
2011/10/9
We examine atmospheric heating by radio active galactic nuclei (AGN) in distant X-ray clusters by cross correlating clusters selected from the 400 Square Degree (400SD) X-ray Cluster survey with radio...
Spectroscopy of Luminous Compact Blue Galaxies in Distant Clusters I. Spectroscopic Data
Spectroscopy of Luminous Compact Blue Galaxies in Distant Clusters I. Spectroscopic Data
2011/10/17
We used the DEIMOS spectrograph on the Keck II Telescope to obtain spectra of galaxies in the fields of five distant, rich galaxy clusters over the redshift range 0.5 < z < 0.9 in a search for luminou...
Simultaneous Falsification of LCDM and Quintessence with Massive, Distant Clusters
Falsification of LCDM Quintessence with Massive Distant Clusters
2010/11/9
Observation of even a single massive cluster, especially at high redshift, can falsify the standard cosmological framework consisting of a cosmological constant and cold dark matter (CDM) with Gaussi...
